it is an outdated SDK. Download a new one from our website and try it.Anyway the recommendation is to run the SDK on real hardware, not the emulator.

ok thanks so much for this issue.

I have another issue regarding Licensing . My app working completely fine till now but currently when i try to run it , it throws me an error "Activation failed . Error : License for this serial number was generated too many times . Please contact Neurotechnology (support@neurotechnoloy.com)” what could be problem and what is solution for it.

Hi,I'm developing a face detection and recognition application by your newest SDK. When I start the application, it crashed. I wonder if it's necessary to obtain related components by the NLicense method because I don't use it in my code.

Hi,Your provided samples can be loaded and started correctly. The logcat says that "library 'libNLicensing.so' not found". But I do include all *.so files from the SDK. I can find the libNLicensing.so in the libs file. I feel quite strange why it can't be found.Thank you.

Hi,

maybe you have mixed *.so files from armeabi-v7a and armeabi.

Hi,After I add NLicense.ObtainComponents method in my code, the application can run correctly. I have solved this issue. Thanks a lot.

Hi,I'm developing an application using the Neurotec_Biometric_5_0_SDK. I enroll the face and save the subjects, which are NSubject[] array. I want to delete one of the subject and I use the delete method in the NBiometricClient. However, the result is wrong, which means it can't be deleted. Please tell me how to do with it. Thank you!

Hello,

could you provide more details (i.e. source code snippet) on what are you doing and what error are you getting?

Hi,My code is refered to your sample FaceActivity. In your sample, when I click the identify button, it lists the enrolled id. If I click one item in the listview, it will identify the person correctly or not. Now I want to change the function of this button to delete a person's id after I click one item and it invoke the following function onSubjectSelected(String id). The detail of related functions is as follows.

This works fine for the first time fingerprint reading but when my code returns "fingerprint mismatch" as result it should ask for try again for next time fingerprint scanning .Here is code to start FingerActivity after result is "fingerprint mismatch" :

Here i provide configuration of two android devices on which i try to test FingerPrint scanning app but it is working on only one device on another device it neither getting scanner device information nor providing scanning area.

Fingerprint scanning app working on "Digiflip pro x811 tablet " but not on "Micromax A114" . Using "USB device info" app i came to know that micromax detect my scanner as usb device but it won't working for my bio metric app. My fingerprint scanning device is "Secugen Hamster plus". What can be problem ?

Does this device support USB Host? If yes, could you provide the full logcat to support@neurotechnology.com with the detailed description of the issue?

Thanks for quick reply . When i check Micromax A114 for USB Host support found that it actually not supporting USB Host . thanks for your help .

We do not support Xamarin at the moment. Please use Eclipse or NetBeans IDE.

Hi: I"ve downloaded your SDK 5.0 for Android ("Neurotec_Biometric_5_0_SDK_Trial_2015-01-09") and have gotten through various issues thanks to past postings in this forum, but can"t find a solution to this problem after running mvn clean install -U on the biometrics-samples-android project:

I have successfully create an sample application for fingerprint identification . My question is usually how much time an application have to take to identify fingerprint when all fingerprints are stored on Sdcard ? i'm asking this question because currently it takes 3 to 5 minutes for matching fingerprint.Or you could just give me an approximate time it takes .

How to check fingerprint is "Misread" or not properly read from scanner or finger has not been placed properly on scanner?

For example finger is placed on finger scanner in such way that scanner may read some of the portion of finger or you can say finger is misplaced on scanner if that is the case i can call it "Misread' but how to identify this case with help of coding ? or which method trigger to capture fingerprint from scanner ?

Hello,

there is no such functionality in the SDK. Some scanners returns various statuses, i.e. CrossMatch Guardian scanners can return if the finger is placed to close to border of the sensor. In case of scanners supported under Android operating system in our SDK, none of the returns such information.

We are testing sample program for android "multibiometric-sample.apk" provided in the SDK installation /Bin/Android folder.We are testing VeriLook app. After capture a photo or load an existing photo, we always get a message "Faces feature points detector file is missing".What this message is all about ?

Hello,

Check if in your device sd_card\Neurotechnology\Data\multibiometric\Faces.ndf file exists. If there isn't that file, then upload from SDK_Folder\Bin\Data folder. If application still won't work then provide SDK revision number, which you can find in SDK root folder in revision.txt file.

I activated the licence a few days ago, and I could run VeriLook application. However, recently when I run this application, it says that licences were not obtained. When I start the licensing manager application, it says that Licensing Manager has crashed. And there comes the following error: External error occurred ExternalError:-1.

Hi all,

I have a similar problem as Helen. I try to use Verifinger standalone on Android.

We do not use maven, so I coppied the file "jna.jar" to the "libs" folder. Furthermore, there are two subfolders of "libs": "armeabi" and "armeabi-v7a" with files "libdatabase_sqlcipher.so", "libsqlcipher_android.so", "libstlport_shared.so". But there is no file "jnidispatch.so".

Where should "jnidispatch.so" be and where do I get this file from?Can someone help me?

Hi,

try to drag and drop both folders from “Lib\Android” to “libs” folder of your project in Eclipse and then rebuild the apk.

Hello,

samples and tutorials are provided within the downloaded SDK. it is recommended to start with tutorials, as they covers smaller amount of functions in one tutorial, while the sample includes almost all functionality in one place.

how to create the template is shown i.e. in tutorial EnrollFingerFromImage. Here you will see that the template is created by using NBiometricClient.CreateTemplate method, where you pass the NSubject with the NFinger in it.

but it is not possible to convert this NTemplate to an FMRecord

Take a look at tutorial NTemplateToFMRecord, where it is shown how to convert the NTemplate to FMRecord
